As you move into refrigeration a lot of things, that are typically overlooked in AC, are more critical. Super heat, subcooling, oil return, infiltration, low ambient operations, etc are things you will have to understand and check on this equipment. It's a bit more complex with some control devices and schemes you may not be familure with but it's a lot of fun if you like to be challenged. Good luck.

That's always fun. Can't handle the pressure then get out of the kitchen! I firmly believe it takes a special person and personality to be able to handle the pressure of those situations and think clearly. Obviously I don't work on things of that magnitude, but the one freezer I have has at least 20k in it.

Can't argue with that. It takes a masochistic fool.

I should know, I've been doing it for over 30 bloody years now.

Mistakes are a part of being human. Appreciate your mistakes for what they are: precious life lessons that can only be learned the hard way. Unless it's a fatal mistake, which, at least, others can learn from. Al Franken, "Oh, the Things I Know", 2002
